Vocabulary intelligence for your platform.

Word Orb API

The largest structured vocabulary dataset available via API. 162,253 words, 601,143 translations across 47 languages, 30,288 knowledge graph links, and 161,763 ethical content ratings — all served from Cloudflare’s edge with sub-50ms latency globally. No origin server, no cold starts, no region lock.

What You Get Per Word

• Core data: Definition, part of speech, etymology, pronunciation (IPA), difficulty level (1-10), usage examples, frequency rank
• Translations: Up to 47 languages per word, with target-language IPA pronunciation and transliteration where applicable
• Knowledge graph: Synonyms, antonyms, related concepts, and semantic clusters with strength-weighted links (0.0-1.0)
• Ethics & compliance: Age-appropriateness rating (child/teen/adult/professional), cultural sensitivity flags by region, content safety classification
• Tone variants: 1,992 tonal adaptations across 12 teaching archetypes and 3 age groups (for words with tone data)
• Visual: Word images for select high-frequency vocabulary (58 currently, expanding)

Enterprise Packages

Five product packages designed for different integration depths. Every package includes a custom demo page at thedailylesson.com/for/your-company with live API widgets.

Orb Verified: The Education Quality Mark

Orb Verified is a certification program for AI and robotics companies that want to demonstrate their education content meets structured quality standards. In a market flooded with AI systems trained on scraped web data, Orb Verified is a trust signal for education buyers — school districts, parents, and institutional purchasers.

The 9 Review Gates

1. Data Provenance: Where does the educational content come from? Is it traceable to primary sources?
2. Content Structure: Is the content organized in pedagogically sound sequences (not random facts)?
3. Multilingual Coverage: How many languages are supported? Are translations human-verified?
4. Age Appropriateness: Is content rated and filtered by age group with documented criteria?
5. Cultural Sensitivity: Are region-specific sensitivities identified and handled?
6. Assessment Validity: Do assessments measure actual learning outcomes, not just engagement?
7. Accessibility: Does the system work for learners with disabilities, low bandwidth, or limited devices?
8. Privacy Compliance: COPPA, FERPA, GDPR compliance for student data
9. Ethical AI: Are AI generation processes transparent and free from harmful biases?

Three Tiers

• Bronze: Basic compliance — passes Gates 1, 4, 5, 8. Content is safe and sourced.
• Silver: Structured integration — passes all 9 gates. Content is pedagogically organized with valid assessments.
• Gold: Deep partnership — Silver plus ongoing data sharing, co-developed content, and published learning outcome evidence.

Active Enterprise Conversations

SoftBank Robotics

NAO and Pepper robots deployed in 70+ countries for education and hospitality. Word Orb provides 47 languages versus SoftBank’s 20 native language capabilities — a 2.35x coverage advantage. The integration concept: Kelly teaches vocabulary through physical robot interactions, with Word Orb powering the linguistic intelligence behind every conversation.

• Contact: Karen Wood-Maris (Sales)
• Package: Word Orb API + Platform Partnership ($2,500-$25,000+/yr)
• Demo: thedailylesson.com/for/softbank-robotics

Cloudflare

The entire LOTD platform runs on Cloudflare infrastructure — 80+ Workers, 49+ D1 databases, 20+ R2 buckets. Built by a single founder. Aly Cabral (VP Developer GTM) has provided a personal introduction to the developer relations team. A co-authored blog post about building this scale as a solo developer is in progress for Developer Week.

• Relationship: Technical partnership + case study
• Story: Solo founder operates 80+ production Workers — one of the largest non-enterprise Cloudflare deployments
